I'd have to send the radio off, cant be doing with hassle like that really. Since this radio will service the Gmaxx and TXT-1, no need for independant front and rear drive, and independant 4ws on the TXT-1 isnt really needed- this aint a crawler after

I might look into regular 4ws for tight turning circles though, depends if I think its worth while for handling- this thing tips quite easily, so it would only be any use at low speed, and low speed aint my idea of fun.
I still have the laser 6 radio that has fully operational self-centering sticks, so Im not without options if I fancy a tinker.
